of you, for example when approaching a traffic
light or a parked vehicle. Also, the system does
not react to oncoming traffic, pedestrians or
other types of potential traffic such as a rider on
horseback. It is also possible that the system
may not detect smaller moving objects such as
motorcycles or bicycles. Be especially alert
when encountering any of these situations as
the system will neither automatically brake, nor
provide a warning to you. Also, be aware that
every decrease in the distance setting allows
your vehicle to come closer to a vehicle in front
of you and requires a heightened amount of
alertness.<
When your vehicle is actively following a vehicle
in front of you, if the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane may also result in accelera-
tion of your vehicle.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any deacti-
vation, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. You should then reactivate the system only
when you are fully aware of the prior speed and
distance settings. reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not
detect this vehicle until it is fully in your lane
ahead of your vehicle.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.

Technology for comfort, convenience and
safety
PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Audible signals and an optical display indicate
that you are approaching an object in front of or
behind your vehicle. To measure the distance,
four ultrasonic sensors are provided in each
bumper. The range of these sensors is approx.
6 ft/2 m. However, an acoustic warning begins
to sound for the sensors at the front and at the
two rear corners at approx. 24 in/60 cm, and for
the center rear sensors at approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed; oth-
erwise, the system may sound the warning of
physical obstacles too late.<
Automatically activating
The system is activated approx. 1 second after
you engage the transmission position R with
the engine running or the ignition switched on.
Wait this short period before proceeding.
Manual activation
Press the button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system switches
off and the LED goes out. You can reactivate the
system manually as needed.
Signal tones
An intermittent signal indicates the distance of
the vehicle from an object being approached.
Thus, an object detected to the left rear of the
vehicle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become shorter.
The signal tone becomes continuous once the
distance to the nearest object falls below
roughly 1 ft/30 cm.
An intermittent tone is interrupted after approx.
3seconds:
>if you remain in front of an object that was
only detected by one of the corner sensors
>if you drive parallel to a wall
Malfunction
The LED in the button flashes and a message
appears on the Info Display. PDC has failed.
Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
PDC with visual warning
You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are displayed there before a
signal tone begins to sound.
iDrive, for principle details, refer to page16.

Cleaning camera
The function of the camera may be affected by
heavy rain and fog, dirt, snow or ice on the lens.
When this occurs, the displayed image on the
Control Display may become gray.
To minimize icing the camera lens is automati-
cally heated. However, it may be necessary to
clean the camera lens manually under severe
weather conditions. When doing so, cautiously
remove any debris, ice or snow. To avoid dam-
age to the lens, do not use sharp or abrasive
instruments to clean ice, snow, or dirt off the
lens.
When the windshield is cleaned with the head-
lamps on, the camera lens area is automatically
sprayed as well. Refer to page65.

If you open the driver's door when the ignition is
switched off, then the exterior lighting is
switched off if the light switch is in position0, 2
or3.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time; otherwise, it may no longer be pos-
sible to start the engine. It is preferable to
switch on the left-hand or right-hand roadside
parking lamps, refer to page101.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
In the switch position3, the system activates
the low beams and switches them on or off in
response to changes in ambient light condi-
tions, for example in a tunnel, at dawn and dusk,
and in case of precipitation. The LED next to the symbol is illuminated when the low beams are
on.
The low beams may be switched on when the
sun is low on the horizon in a clear sky.
The low beams remain switched on
regardless of the ambient light when you
switch on the front fog lamps.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Pathway lighting
After parking the vehicle and switching off the
headlamps, you can use the headlamp flasher
control to activate the low beams for a period of
roughly 40 seconds.
Pressing the button on the remote control,
refer to page32, also switches on the low
beams for approx. 40 seconds. In addition, the
door handle and interior lamps are switched on
for approx. 10 seconds.
Daytime running lamps*
The daytime running lamps light up in posi-
tion0, 1 or3. The light output is lower than with
the low-beam headlamps.
If the light switch remains in position1, then the
parking lamps are lit after the ignition is
switched off.
Adaptive Head Light*

A congenial climate
For almost all conditions, the AUTO program1
offers the optimal air distribution and air vol-
ume. Select an interior temperature that you
find pleasant.
The following section contains more detailed
information on the available setting options.
The settings are stored for the remote key cur-
rently in use.
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well, as well as the adjustment of the air volume. It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program so as to
prevent window condensation as much as pos-
sible.
Intensity of AUTO program
You can adjust the intensity of the AUTO pro-
gram by repeatedly pressing the AUTO button.
Press the button to have the current setting
briefly displayed on the lower status line of the

wish to take advantage of the condensation
sensor.
Defrosting windows and removing
condensation
Quickly remove ice and condensa-
tion from the windshield and front
side windows.
Also switch on the air conditioner.
Residual heat
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off, e.g.
while the vehicle is stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine

Ventilation in rear
Use the lever1 to vary the airflow direction.
For additional information on rear ventilation
options, refer to page107.
Parked car ventilation
The parked car ventilation blows air into the
passenger compartment to reduce interior tem-
peratures.
You can set two different times for the system
to start. The system is operated via iDrive.
It remains switched on for 30 minutes.
Since the system uses a substantial amount of
electrical current, you should refrain from acti-
vating it twice in succession without allowing
the battery to be recharged in normal operation
between uses.
With a preselected switch-on time, the parked
car ventilation is switched on at an outside tem-
perature of 597/156 or greater. When oper-
ated manually, it is ready for use at any outside
temperature, but not during driving.
The air enters the passenger compartment
through the air vents for the upper body in the
dashboard, which can be adjusted for both
direction and airflow. These vents must be
open for the system to operate.
